摘要: 采用中国石油石油化工研究院开发的Pt-Pd/Al2O3加氢精制催化剂对聚α-烯烃PAO40粗产品进行了加氢精制。结果表明:在反应温度240~280 ℃、反应压力4.0~8.0 MPa、体积空速0.1~0.4 h-1、氢油体积比300:1的工艺条件下,PAO40加氢产品的芳烃含量达到国外同类优秀产品水平;PAO40加氢产品经光照30天后不变色,具有较好的光安定性。

Abstract: The PAO40 crude product was hydrogenated using Pt-Pd/Al2O3 catalyst developed by the Petrochemical Research Institute of PetroChina and the optimal conditions were determined. The results show that under the optimized operating conditions of hydrofining which are 240-280 ℃, 4.0-8.0 MPa, LHSV of 0.1-0.4 h-1 and hydrogen /oil of 300(v/v), the hydrogenated PAO40 has a similar aromatic content with the PAO40 products abroad. No Saybolt color changes of the hydrogenated PAO40 are observed after light test for thirty days, indicating its good light stability.

Key words: poly-α-olefin synthetic oil, hydrofining, Pt-Pd/Al2O3 catalyst, aromatic content
